Donald and Susan Sutherland, who opened the first Coldstone Creamery in Tempe in 1988, call what they do an "ice cream experience." That's pretty accurate, given that they do anything and everything with the yummy frozen stuff. They sell smoothies, cakes and shakes. But the biggest draw for ice-cream screamers is probably the custom creations mixed and blended on Coldstone's signature frozen granite stone. Customers choose their favorite ice cream (made fresh daily) and mix in nuts, fruits, candies, cookies or brownies to make their own outrageous concoctions, served in bowls or waffle cones.
